Is it possible to send message to Chrome Extension from Java Desktop Application?

Why does Java run slower on a desktop application than on a server application?

• The response of a Java desktop application is slower than those on JSP and servlets.

• Answer:

  I assume this is a Java Swing application, and the problem is in UI responsiveness. Swing applications typically feel slow and don't look like native applications, as compared with web applications with usually look  like any other other web app implemented in other languages. This is because rendering web applications is much simpler - especially plain JSP pages which render to HTML without JavaScript. They are rendered using browsers, which have been optimized by "the browser wars" - as compared to Swing (and even SWT, I think?) which have not received much development effort. There may also be inherent problems in Swing rendering, though I am not familiar with these since I don't use develop on Java GUIs. If the problem is not about UI responsiveness, but about processing, it could be because the running in server mode on the server side is already working  on efficient, JIT-compiled code. Besides this, it may not even be a Java problem - but something as simple as, the server has more resources to work on the app than your desktop does.
